Kodomo, eh I mean Koromo (old right) XD
Mihoko Fukuji, love that she cares so much about her team mates :3 And she is blond & cute :D
Kana, neko <3 :D
Satomi , wahaha XD
Mako, she is awesome when she takes of her glasses :D
Saki, du`h Cute, nice name and I always get so excited when she picks that brick that requires that insane luck of hers :P
Yuuki, she`s so damn funny :D
Nodoka, becaus she is so damn cute together with Saki (hope they kiss in season 2 XD)
Hisa, love how she plays.

My least favorite character is that annoying flat-chested taco bitch, Yuki. Honestly, Rie Kugimiya has the most annoying voice of any seiyuu in any anime I have ever seen. Kane Ueda was good as Saki. However, her role as Cyborg 001 in 2001's Cyborg 009 was, to put it nicely, a f---ing failure.
